There was a lot of hip-hop history on the latest episode of Snoop Dogg’s GGN as Russell Simmons took over the hot seat. Uncle Rush spoke about doing angel dust and cocaine in his younger days, turning to meditation and veganism (even treating Snoop to some delicious meat-free grub), and the story of how Beastie Boys member Ad-Rock passed a young LL Cool J’s demo tape onto Rush and Rick Rubin, who together founded Def Jam.
